Also, I was going to attach my IMU to an arduino and have it process it all there, then send the processed data via I2C to the CRIO. Im guessing this is just connected by serial to the CRIO? It wouldn't make sense to use up all the ports on the DSC for digital in.

What libraries are you including with it? Labview, C, Java? And what are the specs of the sensors? (+-3gs, +- 2000 degrees/sec)?

And last thing, does it compensate for temperature? I know that the gyro I tested drifted a whole lot, and when tuned, it would untune because the temperature effected it.
We purchased a $15 9DOF IMU on ebay. It is a GY-85 and it has a single I2C interface for all three sensors, which we connected to the DSC. It does not have a processor, but we have implemented Java code on the cRIO for all three sensors. Is the IMU on newegg also a GY-85?
